Is there amber in the Middle Urals?

The article analyses evidences dating back to the 17th - early 20th centuries, which confirm the presence of fossil resins in the Urals. It is shown that previously all of them were mistakenly called «amber». The most complete data on the composition of fossil resins and their physical and chemical properties are given for the Kolchedan occurrence and the Aleksandrovsky Log and Novy Log sites. Samples of the «Kolchedan amber» are krantzit, and the fossil resins from the Alexander Log and Novy Log sites are shraufite. For the remaining selected occurrences, data are not available, which complicates the assignment of resins to certain species. A thorough analysis of the prospects for the tar content of the selected locations is necessary, both on the basis of extensive field search and revision work, as well as a detailed study of the composition, properties and characteristics of the chemical structure of the found fossil resin.
